PHYSICAL STATE; APPEARANCE:
COLOURLESS
COMPRESSED LIQUEFIED GAS

PHYSICAL DANGERS:
The gas is heavier than air
and may accumulate in low ceiling spaces causing deficiency of oxygen.

CHEMICAL DANGERS:
On contact with hot surfaces or flames this substance decomposes forming toxic and corrosive gases
Attacks magnesium and its alloys.

ROUTES OF EXPOSURE:
The substance can be absorbed into the body
by inhalation.

INHALATION RISK:
On loss of containment this gas can cause suffocation by lowering the oxygen content of the air in confined areas.

EFFECTS OF SHORT-TERM EXPOSURE:
Rapid evaporation of the liquid may cause frostbite.
The substance may cause effects on the
cardiovascular system
and
central nervous system
, resulting in
cardiac disorders
and central nervous system depression.
Exposure could cause lowering of consciousness.
See Notes.

ENVIRONMENTAL DATA

This substance may be hazardous to the environment; special attention should be given to its impact on the ozone layer.

N O T E S

High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death.
Check oxygen content before entering area.
The odour warning when the exposure limit value is exceeded is insufficient.
Do NOT use in the vicinity of a fire or a hot surface, or during welding.
Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
Freon 22, Frigen 22, Halon 22 are trade names.
